Mccann Services Inc

Since 1957, we’ve helped Houston residents and businesses stay comfortable through Texas’s changing climate. As a family-owned and operated team, we’re committed to professionalism, integrity, and customer satisfaction. We provide 24-hour HVAC services, including heating and cooling repair, maintenance, and installation, with a focus on understanding the needs of each home or commercial space.

When a heating or cooling issue arises, our priority is to restore comfort promptly. We draw on decades of HVAC experience to diagnose problems accurately and handle everything from minor malfunctions to major repairs. Throughout the process, we communicate clearly and explain the scope and cost of the work before repairs begin. For new air conditioning or heating systems, our experienced professionals assess the space, discuss individual comfort expectations and budget considerations, recommend suitable equipment, and complete the installation with careful attention to detail. We also perform thorough maintenance inspections, clean vital components, and make necessary adjustments to support efficient system operation.

Our services extend beyond temperature control to the quality of the air indoors. We offer indoor air quality solutions designed to address pollutants, allergens, contaminants, and airflow concerns. These options include air purification systems and ventilation strategies selected according to the needs of the space. Whether we’re repairing existing equipment, maintaining an HVAC system, planning a new installation, or helping improve indoor air quality, we approach the work with precision, transparent communication, and respect for the people who rely on us.
